Title:
COMPOSITE COOLING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2007/083562
Kind Code:
A1
Abstract:
Low temperature cooling is performed in a short time. A composite cooling apparatus
is provided with a vacuum cooling means (4) for vacuum-cooling a subject (3) to
be cooled in a cooling chamber (2); a cold blast cooling means (5) for cooling the
subject (3) with cold blast; and a controller (6) for controlling the vacuum cooling
means (4) and the cold blast cooling means (5). The composite cooling apparatus
is also provided with detecting means (7, 27, 26) for detecting the cooling time
of the vacuum cooling means (4), the pressure and the temperature in the cooling
chamber (2), the temperature of the subject to be cooled, or the changed quantity
of the pressure or the temperature in the cooling chamber (2) or that of the temperature
of the subject (3). The controller (6) successively performs cold blast cooling
process by the cold blast cooling means (5), after vacuum cooling process by the
vacuum cooling means (4). When the values detected by the detecting means (7,
27, 26) become set values, the vacuum cooling process is switched to the cold blast
cooling process.
